Presentation

This presentation to summarize the project as shown during the INFN engineers visit in Alcatel premises on 14-15th of June 2001.

_____________________________________________

With this system will be possible to set up 1024 STM-1 bi-directional SNCP protected paths.With the NMS will be possible to monitor alarms, to perform remote commands and to set up the necessary paths and protection.

Alcatel Equipment

Alcatel Equipment:

Transmission:1660SM (STM-4/16 Node Equipment)1686WM (32 DWDM Equipment)

Network Management System:1353SH (Element Manager Layer)1354RM (Network Manager Layer)

1660SM

Each 1660SM will be equipped with 16 Optical STM-1 tributary to the tower that will be protected with EPS N+1 and 2 Optical STM-16 (Colored) interfaces to the DWDM systems for the SNCP protection.All common cards are protected EPS 1+1.

Subrack Size = 482W x 250D x 650H mm

Consume = 211W (if equipped with 16xSTM-1 + 2xSTM-16)

1660SM - Optical STM-1 module

This Optical Module (S-1.1) will be used as Electrical/Opticalconverter within the customer equipment in both sides, undersea and in the landing station.

Consume = 1,5 W

One module for eachfloor of the tower.

One module for eachreceiver in the landing station.

1686WM

These equipment are used to concentrate 16xSTM-16 channel to one lambda.4x1686WM are necessary to carry the main traffic and other four to carry the protection.A booster +14/+17dB will be necessary depending on the real length of the submarine cable.

Subrack Size = 482W x 250D x 400H mm

Consume = 90W (if equipped with 16 and a +14dB booster)
